Resistivity
Resistance is the physical property of the material which opposes the current flow in the circuit whereas resistivity is the intrinsic property that helps us understand the relation between the dimension of the substance and the resistance offered by it.
In this article, we will learn about Resistance, Resistivity, how resistance and resistivity are related to each other, the difference between resistance and resistivity, and others in detail.
